54347649 ÷ 807 
We're looking to find how many times 807 goes into 54347649.

Advancing to step 1:
807 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 807

Step 2:
807 goes into 54 0 times with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 807

Moving on to step 3:
543 divided by 807 is 0 with a remainder of 543.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 543 to get 543.
Take the next digit (4) from the dividend and append it to 543, then repeat: 5434 / 807

Advancing to step 4:
The number 807 fits into 5434 6 times, leaving a remainder of 592.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 592 after subtracting 4842 from 5434.
Include the next digit (7) from the dividend after 592, then repeat: 5927 / 807

Advancing to step 5:
If we divide 5927 by 807, we get 7 and a remainder of 278.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we subtract 5649 from 5927, we get 278.
Grab the next digit (6) from the dividend, add it to 278, then carry on: 2786 / 807

Going ahead to step 6:
When dividing 2786 by 807, we get 3 with a remainder of 365.
Use 3 as the next digit of our solution. 
Result so far: 673.0
Subtracting 2421 from 2786 leaves us with 365.
Append the next digit (4) from the dividend to 365 and continue with: 3654 / 807

Step 7:
The number 807 fits into 3654 4 times, leaving a remainder of 426.
The number 4 becomes the next digit in our result. 
Result so far: 6734.0
The remainder is 426 after subtracting 3228 from 3654.
Bring next digit (9) of the dividend behind the 426 and repeat the process: 4269 / 807

Moving on to step 8:
4269 divided by 807 is 5 with a remainder of 234.
Record the quotient 5 as the next digit in the result. 
Result so far: 67345.0
Subtracting 4035 from 4269 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 9:
807 goes into 2340 2 times with a remainder of 726.
The next digit of our result is 2. 
Result so far: 67345.2
Subtract 1614 from 2340 to get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Step 10:
The number 807 fits into 7260 8 times, leaving a remainder of 804.
Record the quotient 8 as the next digit in the result. 
Result so far: 67345.28
If we subtract 6456 from 7260, we get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Let's proceed to step 11:
When dividing 8040 by 807, we get 9 with a remainder of 777.
Record the quotient 9 as the next digit in the result. 
Result so far: 67345.289
Subtracting 7263 from 8040 leaves us with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

On to step 12:
7770 divided by 807 is 9 with a remainder of 507.
The next digit of our result is 9. 
Result so far: 67345.2899
If we subtract 7263 from 7770, we get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

After the division, we end up with 67345.2899 and a remainder of 0.00507.
